Application
SURFACE PREPARATION: Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove surface contaminants, i.e. dust, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials.
Concrete: Sandblast or use other approved mechanical means.
Steel: Sandblast to white metal finish.
MIXING: Pre-mix each component thoroughly. Place 1 part by volume of component A and 1 part by volume of component B into a clean pail. Mix thoroughly for 3 min. with low-speed drill (400-600 rpm) until uniformly blended. Mix only the quantity that can be used within its gel time.
TO APPLY: Pour PRO-FLEX into joints or cracks or use low pressure application equipment.

Limitations
- Minimum surface temperature is 40°F/5°C
- For best results, use between 65° and 85°F/18-29°C
- Do not thin. Solvents will prevent proper cure.
- Material is a vapor barrier after cure.
- Minimum age of concrete should be 21-28 days.
- Not for sealing cracks under hydrostatic pressure.
- Not to be used in moving cracks or expansion joints.

Cleanup
EQUIPMENT: Uncured material can be removed with Unitex CITRI-CLEAN or other approved solvent. Cured material can only be removed mechanically.
MATERIAL: Collect with absorbent material. Flush area with water. Dispose of in accordance with local, state and federal disposal regulations.
